You wouldn’t want to put a lawnmower engine in a Lamborghini, or vice versa. So when Swedish SKF sells precision bearing solutions for demanding heavy duty applications, it recommends high performance bearing housings to match.

A housing, which is static, holds the bearing, lubricating it and protecting it from dust and water. In mining applications such as elevators and conveyor belts, both bearing and housing are subjected to intense vibrations and massive loads.

For its new SED modularised bearing housings, which can weigh anywhere from 2 to 7 tons, SKF’s Mekan division fits Superbolt multi-jackbolt tensioners from the Nord-Lock Group as standard. Four are fitted to each housing, allowing for easy assembly and maintenance, which is crucial when the housing is fitted 50m above ground in an elevator tower or hundreds of metres below it in a mine.

SKF Mekan’s customers, which includes other companies with similarly inaccessible installations, appreciate the fact that one person using a hand-held torque wrench can quickly and safely install the multi-jackbolt tensioners. And they know the joint is secure, even in the harshest operating conditions.
